Moto 6120 here as well. Though my local cable carrier has a specific list of approved modems. So the reseller ISP I have only allows certain ones, and on top of that certain firmware levels. Same reseller ISP in another region has a different local cable carrier, so diff list of modems AND firmwares etc etc if you live there. In short, be carefull the model and FW will work I guess. If I bought a 6120 from Ontario it wouldn't be stable in Quebec. BUT if I bought a 6120 from Quebec and lived in Ontario the carrier would push the FW change (not the case the other way around).
